    Review Cite This: Ind. Eng. Chem. Res. XXXX, XXX, XXX−XXX pubs.acs.org/IECR 110th Anniversary: Carbon Dioxide and Chemical Looping: Current Research Trends Lukas C. Buelens, Hilde Poelman, Guy B. Marin, and Vladimir V. Galvita* Laboratory for Chemical Technology, Ghent University, Technologiepark 125, B-9052 Ghent, Belgium *S Supporting Information ABSTRACT: Driven by the need to develop technologies for converting CO2, an extraordinary array of chemical looping based process concepts has been proposed and researched over the past 15 years. This review aims at providing first a historical context of the molecule CO2, which sits at the center of these developments. Then, different types of chemical looping related to CO2 are addressed, with attention to process concepts, looping materials, and reactor configu- rations. Herein, focus lies on the direct conversion of carbon dioxide into carbon monoxide, a process deemed to have economic potential. 1. THE DISCOVERY OF CARBON DIOXIDE designate CO2 and CO probably occurred only after the Carbon dioxide was probably discovered around 1640 by Jan foundation of the International Union on Pure and Applied Baptist van Helmont, who named it spiritus sylvestre.1,2 When Chemistry (IUPAC) in 1919. burning a piece of wood, van Helmont noticed that the mass of 1,2 2. CARBON DIOXIDE AND THE EARTH’S CLIMATE the ash was considerably less than that of the original wood. He argued that a gas had volatilized from the wood.1,2 Over a In the 1820s, Joseph Fourier made heat transfer calculations hundred years later, around 1750, Joseph Black looked into based on knowledge of that time−between the Sun and the 9,10 carbon dioxide released by magnesium carbonate upon heating Earth.

F. Maher Johnson Matthey Technology Centre High temperature superconducting oxides are being subjected to intensive investigation, designed to establish the basic mechanisms governing their superconductivity and to enable their electrical and mechanical proper- ties to be optimised and commercial applications developed. Chemical composition, crystallography, microstructure and the concentration of point defects are all factors that have a crucial bearing on superconduc- tivity. Progress in fabrication and thermal processing would elevate these high temperature superconducting oxides from laboratory curiosities to a position where widespread commercial use could be envisaged. Much has already been published on the use of the platinum group metals with the new superconductors. This article has been compiled from a search of the literature and indicates some of the applications that are, or could be, of commercial significance.

    Proceedings International Journal of Nanomaterials, eertechz Nanotechnology and Nanomedicine Special Issue: NCNN-2014 (National Conference on Nanoscience and Nanotechnology - 2014) First Principles Study of Th ermal and Vibrationalfrequencies and Bonding Analysis in Oxides (M2O) Superosides (MO2) and Ozonides (MO3); (M=Li, Na, K) Shiba Subedi*, Jeevan Jyoti Nakarmi Central Department of Physics, Tribhuvan University Kathmandu Nepal, E-mail: [email protected] www.peertechz.com First-principles calculations in order to study the stability of oxides, superoxide and ozonide of alkali metals (Li, Na, K) has been performed by HF cluster procedure implemented by Gaussian 09 sets of programs with the choice of basis set 6-31G*. The correlation effects in the calculations have been accounted by applying Moller-Plesset second order perturbation approximations (MP2). Our calculation shows that when increasing the bond length between atoms of molecules, the binding energy of the corresponding system decreases, i.e. the stability of the studied system is inversely proportional to the bond length between the atoms of the corresponding system. Quantum Theory of Atoms In Molecule (QTAIM) approach has been adopted for bonding analysis for studied systems and this study shows that the bonding in all studied systems are of closed shell type at all. Our study for the variation of the real space function with bond length fi nds that with increase in bond length the real space function values at BCP (ρ and 2ρ) found to be decrease, which are in close agreement with the previously reported calculations. The electrostatic potential within the molecular surface of the studied systems has been systematically analysed.
